Description

Technical Field

[0001] This invention relates to an integrated dosing and pressurizing device, belonging to the technical field of pressurizing equipment. Background Technology

[0002] In oilfield development, wellhead chemical dosing is a crucial step in ensuring normal well operation and improving oil production efficiency. Currently, wellhead chemical dosing in oilfields mainly employs two methods: manual dosing and manual dosing pumps. However, these traditional methods have the following problems: High labor intensity: Manual application of chemicals requires a large number of people, the operation is cumbersome, the labor intensity is high, it can easily lead to operator fatigue, and affect work efficiency.

[0003] Uneven dosing flow rate: When using a manual dosing pump, the dosing flow rate is difficult to maintain due to the instability of human operation, which prevents the drug from achieving its full effect and results in waste of the drug.

[0004] Chemical waste: Due to uneven dosing flow rate, the chemical cannot be evenly distributed, resulting in excessively high chemical concentrations in some areas and excessively low chemical concentrations in others, failing to achieve the expected treatment effect and causing chemical waste.

[0005] Improper operation: The models and sizes of chemical dosing pumps used by different oil production plants and oil production stations on site are inconsistent, and there are no unified operating standards, which can easily lead to operational errors, affect the dosing effect, and even cause safety accidents.

[0006] Safety hazards: Due to improper operation, there may be safety hazards during the dosing process, such as chemical leakage and equipment damage, which pose potential threats to operators and the environment.

[0007] Furthermore, at oilfield production sites, freezing or blockages frequently occur in localized processes due to technological processes or low temperatures. The conventional unblocking operation involves using boiler trucks and tank trucks to sweep and clear the blockages, but this method has the following problems: Low efficiency: Boiler trucks and tank trucks require a lot of equipment and manpower to clean up blockages on the production line. The operation is complicated, inefficient, and cannot restore production in a timely manner.

[0008] High cost: Using boiler trucks and tank trucks for line cleaning and unblocking requires a large amount of fuel and water resources, which is costly and increases production costs.

[0009] When problems arise with the downhole tubing and further assessment is needed, it is often necessary to request the use of a cement truck and a tanker truck to pressure test the tubing to determine the downhole fault. This method has the following problems: The equipment is bulky: cement trucks and tank trucks are large and difficult to move, making them difficult to operate in narrow work sites.

[0010] Complex operation: Using cement trucks and tank trucks to pressurize oil pipelines is a complex operation that requires professional operators, increasing the difficulty and time cost of operation.

[0011] High costs: The high operating costs of cement trucks and tank trucks increase production costs and are not conducive to improving economic efficiency.

[0012] In summary, existing methods for chemical dosing, line clearing and unblocking, and tubing pressurization in oilfield wells have many problems, and there is an urgent need for a more efficient, convenient, and safe integrated chemical dosing and pressurization device to solve these problems.

[0061] This embodiment provides an improved pressing mechanism. The similarities to Embodiment 1 are not described here. The differences from Embodiment 1 are: Please refer to... Figure 4 , Figure 5 The pressing mechanism includes a pressing box 81, a drive motor 82, a one-way feed pipe 84, a one-way discharge pipe 83, and a pressing plate 811. The pressing plate 811 is slidably and sealedly connected inside the pressing box 81. The drive motor 82 is located on one side of the pressing box 81 and is used to drive the pressing plate 811 to reciprocate axially. The pressing box 81 is provided with a rotatable rotating tube 812. The side wall of the rotating tube 812 is provided with multiple through-type adjustment slots 8121. The inner end of the flow equalization tube 813 is inserted into the adjustment slot 8121, and the front and rear sides of the flow equalization tube 813 near the inner end are hinged to the inner wall of the adjustment slot 8121 by short pins, so that the end of the flow equalization tube 813 can swing up and down around the axis of the short pins.

[0062] The flow equalization pipe 813 is provided with multiple water distribution holes 8131, and the regulating groove 8121 is provided with a sealing ring 8122 that is elastic for sealing. The sealing ring 8122 is sealed to the outer wall of the flow equalization pipe 813. The one-way feed pipe 84 is connected to the inner cavity of the rotating pipe 812. The outlet of the pressure box 81 is provided with a connected one-way discharge pipe 83, which is connected to the outlet coil.

[0063] The design of the pressure box 81, pressure plate 811, one-way feed pipe 84, and one-way discharge pipe 83 enables the pressure box 81 to pressurize and transport the medicine by utilizing the reciprocating motion of the pressure plate 811 and the cooperation of the one-way feed pipe 84 and the one-way discharge pipe 83. The design of the rotating pipe 812, short pin shaft, and flow equalization pipe 813 allows the medicine to enter the pressure box 81. With the rotation of the flow equalization pipe 813, the liquids of different components can be fully mixed and evenly. This ensures that the medicine is fully mixed and evenly mixed before being dispensed, thereby maximizing its efficacy.

[0064] In this embodiment, please refer to Figure 5 , Figure 6One end of the rotating tube 812 is rotatably connected to the inner wall of the pressure testing box 81, and the pressure testing box 81 is equipped with a drive mechanism for rotating the rotating tube 812. The rotating tube 812 contains a rotatable positioning rod 815, with a reciprocating thread 8151 on its outer circumference. A matching positioning inner sleeve 8152 is fitted around the positioning rod 815, and the positioning inner sleeve 8152 is connected to the positioning rod 815 via the reciprocating thread 8151. The rotating tube 812 contains a guide rod 8155 fixedly connected to the bottom wall of the pressure testing box 81. The guide rod 8155 slides through the positioning inner sleeve 8152, allowing the positioning inner sleeve 8152 to move only axially. The inner positioning sleeve 8152 is rotatably connected to the outer positioning sleeve 8154. The outer positioning sleeve 8154 is further connected to multiple rotatably connected telescopic rods 8153. The ends of the telescopic rods 8153 are rotatably connected to the ends of the flow equalization pipe 813. The bottom wall of the pressure box 81 has a first hole communicating with the inner cavity of the rotating pipe 812. A one-way feed pipe 84 is connected to this first hole. Two one-way feed pipes 84 are provided, one for feeding chemicals and the other for feeding clean water.

[0065] By rotating the positioning rod 815, cooperating with the reciprocating thread 8151, and with the limiting of the guide rod 8155, the positioning inner sleeve 8152 can periodically move up and down along the positioning rod 815. With the traction of the telescopic rod 8153, the flow equalization pipe 813 can swing up and down around the short pin shaft while rotating with the rotating pipe 812, so that the flow equalization pipe 813 can mix the medicine in the pressure box 81 more thoroughly.

[0066] In this embodiment, please refer to Figure 5 The flow equalization pipe 813 is equipped with a slidingly connected cleaning ring plate 8132, and the end of the flow equalization pipe 813 is equipped with a baffle to prevent the cleaning ring plate 8132 from slipping off. The inner wall of the cleaning ring plate 8132 is equipped with cleaning bristles for cleaning the water distribution holes 8131. The cleaning ring plate 8132 is made of a material with a certain weight. The design of the cleaning ring plate 8132 allows the cleaning ring plate 8132 to move back and forth along the flow equalization pipe 813 under the action of gravity as the flow equalization pipe 813 swings up and down around the short pin shaft, effectively preventing impurities from remaining on the flow equalization pipe 813 and also cleaning the water distribution holes 8131 to prevent clogging.

[0067] In this embodiment, please refer to Figure 4 The output end of the drive motor 82 is provided with a fixedly connected drive disk 821. A connecting rod 822 is hinged to the drive disk 821, and the other end of the connecting rod 822 is hinged to the pressure plate 811. The drive motor 82 causes the drive disk 821 to rotate, one end of the connecting rod 822 follows the drive disk 821 to make a circular motion, and the other end of the connecting rod 822 drives the pressure plate 811 to make a periodic reciprocating motion.

[0068] In this embodiment, please refer to Figure 5 The outer periphery of the root of the rotating tube 812 is fitted with an annular cylinder 814. The center of the top wall of the annular cylinder 814 is rotatably supported on the outer wall of the rotating tube 812 and is sealed to each other. The lower end of the annular cylinder 814 is rotatably embedded in the groove of the bottom wall of the pressure box 81 and is sealed to each other. The outer periphery of the annular cylinder 814 is provided with multiple discharge pipes 8142 that communicate with its inner cavity. Multiple discharge holes 8141 are provided on the discharge pipes 8142. The pressure box 81 is provided with a second hole that communicates with the inner cavity of the annular cylinder 814. The outer side of the second hole is connected to the one-way discharge pipe 83.

[0069] In this embodiment, please refer to Figure 5 , Figure 7 The driving mechanism includes a driving rod 816, a first helical rod 8161, and a first driving ring 8162. One end of the driving rod 816 is fixedly installed at the center of the pressure plate 811. One end of the rotating tube 812 is provided with a driving groove 8165 that slides and is sealed to the driving rod 816. The inner wall of the driving groove 8165 is provided with a first limiting ring groove that is connected to the first driving ring 8162. The end of the driving rod 816 is provided with a helical first helical rod 8161. The first helical rod 8161 is matched and connected to the first driving ring 8162. When the first helical rod 8161 passes through the first driving ring 8162, it drives the first driving ring 8162 to rotate.

[0070] Utilizing the spiral shape, the drive rod 816, while moving axially with the pressure plate 811, drives the first drive ring 8162, which in turn drives the rotating tube 812 to rotate continuously in both directions. The spiral design is based on the spiral design found in existing technologies, such as those used in hand-operated bamboo dragonflies; therefore, this application will not describe it in detail. Example

[0071] This embodiment is a further optimization based on Embodiment 2. Please refer to [link / reference]. Figure 5 , Figure 7 The drive groove 8165 extends downward to the center of the end of the positioning rod 815. The end of the drive groove 8165 located in the positioning rod 815 is provided with a second limiting ring groove. The second limiting ring groove is provided with a second drive ring 8164 that is unidirectionally rotatably connected. The end of the first spiral rod 8161 is provided with a spiral-shaped second spiral rod 8163. The second spiral rod 8163 is matched and connected with the second drive ring 8164. When the second spiral rod 8163 passes through the second drive ring 8164, it causes the second drive ring 8164 to rotate.

[0072] The design of the second drive ring 8164 and the second helical rod 8163, as well as the unidirectional rotational connection between the second drive ring 8164 plate and the second limiting ring groove, allows the drive rod 816 to drive the second drive ring 8164 to rotate while simultaneously driving the positioning rod 815 to rotate synchronously during the downward movement of the drive rod 816. When the drive rod 816 moves upward, it drives the second drive ring 8164 to rotate in the opposite direction. At this time, the second drive ring 8164 will not drive the positioning rod 815 to rotate. This design enables the positioning rod 815 to continuously rotate in the same direction, allowing the positioning rod 815 to periodically drive the positioning inner sleeve 8152 to move up and down.

[0073] In this embodiment, please refer to Figure 8 An external gear ring 8123 is fixed to the outer wall of the rotating tube 812 within the annular cylinder 814. An internal gear ring 8143 is fixed to the inner circumferential wall of the annular cylinder 814. The external gear ring 8123 and the internal gear ring 8143 mesh through an intermediate gear 8144. That is, one side of the intermediate gear 8144 meshes with the external gear ring 8123, and the other side meshes with the internal gear ring 8143. The external gear ring 8123, the intermediate gear 8144, and the internal gear ring 8143 are all located within the annular cylinder 814. The design of the external gear ring 8123, the intermediate gear 8144, and the internal gear ring 8143 allows the flow equalization tube 813 and the discharge tube 8142 to rotate in opposite directions. This design allows for more thorough mixing of the medicine in the pressure chamber 81.

[0074] When using this device: During spraying, the outer end of the one-way feed pipe 84 is connected to the corresponding medicine tank and water tank. Then, the drive motor 82 is started, which drives the pressure plate 811 to reciprocate periodically. Through the reciprocating motion of the pressure plate 811, in conjunction with the one-way valves in the one-way feed pipe 84 and the one-way discharge pipe 83, the material in the medicine tank and water tank can be automatically drawn into the one-way feed pipe, then enters the inner cavity of the rotating pipe 812, and then enters the inner cavity of the flow equalization pipe 813 through the rotating pipe 812. Next, it enters the pressure box 81 through each water distribution hole 8131, and finally enters the discharge pipe 8142 through the discharge hole 8141. It then enters the one-way discharge pipe 83 through the discharge pipe 8142 and is discharged. Finally, it is discharged through the outlet coil for normal spraying.

[0075] During the reciprocating motion of the pressure plate 811, the pressure plate 811 can drive the drive rod 816 to perform synchronous axial periodic reciprocating motion. The periodic reciprocating motion of the drive rod 816 can drive the first drive ring 8162 plate to rotate periodically forward and backward through the first spiral rod 8161. This allows the rotating tube 812 to rotate periodically forward and backward during the process of the medicine entering the pressure box 81, so that the flow equalization tube 813 can stir and mix the medicine entering the pressure box 81. At the same time, through the meshing transmission of the outer gear ring 8123, the intermediate gear 8144 and the inner gear ring 8143, the discharge tube 8142 can rotate synchronously and periodically forward and backward, and the rotation direction of the flow equalization tube 813 and the discharge tube 8142 is opposite, which can better mix the medicine.

[0076] Simultaneously, the periodic reciprocating motion of the drive rod 816 can also synchronously drive the second drive ring 8164 to rotate periodically in both directions via the second helical rod 8163. Since the second drive ring 8164 and the second limiting ring groove are connected in one direction, the second drive ring 8164 will only drive the positioning rod 815 to rotate in the same direction. Thus, under the action of the reciprocating thread 8151 and due to the limiting of the guide rod 8155, the positioning inner sleeve 8152 can periodically move up and down, thereby driving the end of the flow equalization tube 813 to swing up and down, which can further improve the mixing efficiency of the medicine and facilitate the cleaning of the outer wall of the flow equalization tube 813.
